Earlier civilization

Civilization was a time of human forming society. For the first time, large number of people came together and started developing community and leaders. Around the world people started producing foods and started writing. In 900 B.C.E there was a first written language in America. At that time agriculture was the foundation of economic. Wealth, power, and status divided the people of civilization and started facing inequality. For example, in South Asia there was a cast system. On the other hand, written language made it easier for historians to know about earlier histories. But before the historian had to predict the information because there were not much evidence. Today people can still survive with technologies like car, phone, and internet, but technology are making people life. I think we have to change when the time change other wise we will be behind. The time part our past cultures and thoughts of people are changing for 'better.'
